Emit the new `local_query` tuple only if query options are set #451

Why

Using the new tuple isn't compatible with older versions of Ra. This breaks local/leader queries if there are Ra members running an old version.

How

We don't need the new {local_query, QueryFun, Options} tuple if there is no options. We can use the old {local_query, QueryFun} in this case and keep the compatibility.
